How can i use your API in front POST?

Hi guys. Thank you very much for good job. It’s very good API. But i’m a noob in FrontEnd and can’t understand how i can use your API. I mean. First question : What different between /public and /private? Second : i have code in my VUE client

import axios from 'axios';
export default {
  data () {
    return {
        form: {
        username: '',
        password: '',
      },
    }
  },
 methods: {
    onSubmit (evt) {
      evt.preventDefault()
      // this.$router.push('/home')
    axios.post(`http://localhost:3003/api/login`, this.form)
    .then(response => {
      // JSON responses are automatically parsed.
      this.form = response.data
      sessionStorage.setItem('token',response.data.token);
      this.$router.push('/home')
    })
    .catch(e => {
      console.log(e)
    })
    }
  }

And i have troubles only with Login. Auth service work good. What i have to do for use your api? Can’t understand. Sry for my noobs qust. And thank you for listening. P.S. and ofc. sry for bad eng, from Russia.

i do not really understand the question…

but you are using here the username as key for the data you post to the server… you should change username to email, but maybe you have to change something in your app somewhere else too…

 data () {
    return {
        form: {
        username: '',
        password: '',
      },
    }
  },
